Why: To protest the DARK Act, (H.R. 1599), a bill introduced by Rep. Mike Pompeo (R-Kan.) and written by Monsanto, that would strip states of the right to pass GMO labeling laws; to call for a global ban on Monsanto’s Roundup herbicide; to call for an end to Monsanto’s global seed monopoly and toxic monocultures.

In June, Congress will hold its first vote on H.R. 1599, The Safe and Accurate Food Labeling Act. Critics call it the Deny Americans the Right to Know (DARK) Act because that’s what it’s designed to do—keep consumers in the dark about the GOs in their food.

In March, the World Health Organization declared glyphosate, the key active ingredient in Roundup, a probable carcinogen. Roundup is the most widely used herbicide in the world, even though it has been linked to cancer, kidney and liver disease, infertility, chronic digestive disorders and other illnesses.

Citizens in Miami, Florida will join millions of people from around the world on May 23, to march against Monsanto’s support for the DARK Act, and to call for a ban on Monsanto’s Roundup herbicide.
